Description

Technical Field

[0001] This utility model relates to the field of pharmaceutical packaging quality inspection technology, specifically a conveying device for inspecting the quality of pharmaceutical aluminum-plastic plate packaging. Background Technology

[0002] Aluminum-plastic packaging machines are used for blister packaging of capsules, unpackaged tablets, sugar-coated tablets, soft capsules, injections, irregularly shaped tablets, as well as medical devices, light chemical foods, and electronic components. Especially for unpackaged tablets, aluminum-plastic packaging machines may encounter issues such as missing tablets, damaged tablets, or tablets standing upright after packaging, affecting product quality and requiring rejection. However, the blister packs in aluminum-plastic packaging machines are often located at the bottom, requiring flipping to access the tablets. Manually flipping the blister packs is inefficient and labor-intensive. Chinese patent application CN202022942948.2 discloses an automatic blister pack flipping device for aluminum-plastic packaging machines that automatically flips the blister packs after packaging to inspect the tablets and reject defective products. However, this mechanism is complex, and the flipped blister packs still require manual quality inspection, resulting in high labor costs and intensity. Therefore, this case arose from in-depth research into these issues. Utility Model Content

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Example: Refer to the appendix of the instruction manual Figure 1-4As can be seen, this application specifically designs a conveying device for quality inspection of aluminum-plastic packaging of pharmaceuticals, including a packaging conveyor 1 installed at the discharge end of an aluminum-plastic packaging machine, and a quality inspection conveyor 2 installed below the packaging conveyor 1. The quality inspection conveyor 2 and the packaging conveyor 1 are arranged alternately in the vertical direction. A vertical frame 3 is installed on the frame of the quality inspection conveyor 2, and a horizontal adjustment component is installed on the side wall of the vertical frame 3. An arc-shaped material guide groove 4 is installed on the moving end of the horizontal adjustment component. The inner ring end face of the arc-shaped material guide groove 4 is flush with the packaging conveyor. The outlet end of conveyor 1 has its belt surface in contact with the surface of the conveyor belt. The outlet end of the arc-shaped guide chute 4 is located above the belt surface of the quality inspection conveyor 2. Arc-shaped baffles 5 are symmetrically arranged on both sides of the quality inspection conveyor 2. A mounting frame 6 is installed on one side of the arc-shaped baffle 5. An industrial camera 7 is installed on the top of the mounting frame 6. The industrial camera 7 has a built-in vision inspection module. A pneumatic rejection assembly is installed on the side wall of the mounting frame 6. A guide chute 8 is installed on one side of the pneumatic rejection assembly. A defective product collection hopper 9 is installed below the guide chute 8. The medicine blister packs packaged by the aluminum-plastic packaging machine pass through the packaging... The tablets are moved out of the conveyor 1 and placed into the arc-shaped guide chute 4. As the tablets pass through the arc-shaped guide chute 4, they slide along the arc surface and automatically flip over. After flipping, the tablets are driven by the belt of the quality inspection conveyor 2 and pass through the arc-shaped baffle 5. The arc-shaped baffle 5 makes the tablets more neatly arranged. The tablets then pass through the industrial camera 7, which takes pictures of the tablets. Using a vision inspection module in conjunction with the industrial camera 7 and AI algorithms, the images of each tablet are analyzed to identify empty tablets. If defects such as bubbles or half-grains exist, the defective blister pack is sent into the defective product collection hopper 9 by the pneumatic rejection assembly. The horizontal position of the arc-shaped guide trough 4 can be adjusted by the horizontal adjustment assembly to ensure that the inner ring end face of the arc-shaped guide trough 4 is in contact with the outlet belt surface of the packaging conveyor 1, thereby improving the stability of operation. In addition, when it is necessary to maintain equipment such as the quality inspection conveyor 2 or the packaging conveyor 1, the arc-shaped guide trough 4 can be moved out of its current position to facilitate smooth maintenance.

[0018] In a preferred embodiment, the aforementioned horizontal adjustment assembly includes a fixed base 10, a transmission control component, a movable base 11, and a guide component. The fixed base 10 is mounted on the upright frame 3, the transmission control component is mounted on the fixed base 10, the movable base 11 is mounted on one end of the transmission control component and is assembled and connected to the side wall of the arc-shaped guide channel 4, and the guide component is symmetrically arranged on both sides of the transmission control component with one end connected to the movable base 11. The transmission control component includes a lead screw nut 12, a transmission lead screw 13, and a handwheel 14. The lead screw nut 12 is embedded in the fixed base 10, the transmission lead screw 13 spirally passes through the lead screw nut 12 and is rotatably connected to the movable base 11, and the handwheel 14 is fixed on the exposed end of the transmission lead screw 13. The aforementioned guide component includes a guide sleeve 15 and a guide... The guide column 16 and guide sleeve 15 are symmetrically arranged on both sides of the fixed seat 10. The guide column 16 is slidably inserted into the guide sleeve 15 and one end is connected to the movable seat 11. In use, the handwheel 14 is used to rotate and adjust the transmission screw 13, so that the transmission screw 13 moves horizontally under the limiting action of the screw nut 12. This drives the movable seat 11 and the arc-shaped material guide channel 4 at one end of the movable seat 11 to move horizontally under the cooperation of the guide columns 16 on both sides, so as to achieve the contact between the end face of the arc-shaped material guide channel 4 and the belt surface of the packaging conveyor 1. When it is necessary to maintain the quality inspection conveyor 2 or the packaging conveyor 1, the handwheel 14 can be rotated in the opposite direction to move the arc-shaped material guide channel 4 out of the current position, so as to facilitate the smooth maintenance.

[0019] In the specific implementation process, as a preferred configuration, the above-mentioned pneumatic rejection assembly includes a support 17, a cylinder 18, and a pusher plate 19. The support 17 is set on the side wall of the mounting frame 6, the cylinder 18 is set on the support 17 in a horizontal direction, and the pusher plate 19 is set on the telescopic end of the cylinder 18. When the vision inspection module built into the industrial camera 7 detects that there is a quality problem with the medicine plate, it sends an electrical signal to the controller. The controller controls the telescopic end of the cylinder 18 to expand, thereby pushing the current defective medicine plate into the guide groove 8. Under the dual action of horizontal thrust and gravity, the medicine plate enters the defective product collection hopper 9.

[0020] In the specific implementation process, as a preferred setting, the guide groove 8 is an L-shaped inclined groove with a transition plate 20 at one end. The transition plate 20 extends into the belt surface of the quality inspection conveyor 2, which can effectively improve the efficiency of rejecting defective medicine plates and prevent medicine plates from getting stuck between the belt of the quality inspection conveyor 2 and the guide groove 8.
